public FrequencyPattern(Vector3D eccentricities,
                        PhaseCenterVariationFunction phaseCenterVariationFunction)
```
    Simple constructor.
    
    Parameters:
    
    eccentricities - phase center eccentricities (m)
    
    phaseCenterVariationFunction - phase center variation function (may be null if phase center does not depend on signal direction)

```
public Vector3D getEccentricities()
```
    Get the phase center eccentricities.
    
    Returns:
    
    phase center eccentricities (m)
  - getPhaseCenterVariationFunction
```
public PhaseCenterVariationFunction getPhaseCenterVariationFunction()
```
    Get the phase center variation function.
    
    Returns:
